BOLT-RETAINER.

Specification of Letters Patent.

Patented March 19, 1907.

Application filed July 2. 1906. Serial No. 324,315.

To all whom it may concern:

Be it known that I, JOHN HARTMAN, a citizen of the United States,residing at Morral,

in the county of Marion and State of Ohio,

have invented certain new and useful Imrovements in Bolt-Retainers; andI do'herey declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The object of this invention is to provide means for holding orretaining bolts from r0- tation while the nuts are being turned up onthem. 1

The invention consists in the construction hereinafter described andclaimed, the in.- vention not being confined in its embodiment to theparticular forms and proportions of parts illustrated in theaccompanying drawings.

In said. drawings, Figure 1 is a view in elevation of the outer side ofthe device. Fig. 2 is an edge view, partly in section, illustrat ing howthe device is used. Fig. 3 is a transverse section on the line 90 at,Fig. 1, looking to the right. Fig. 4 is a side view of one of theretainers, showing how it is adapted to a bolt having a head of largersize than that illustrated in Fig. 1..

As each side of the retaining device is the symmetrical duplicate of theother, a description of one will suffice for both.

In the views, 1 designates the retainerframe. This frame is ofrectangular form with a rectangular opening and. is .rovided in one sideof the opening with a series of flat bars 2, placed side by side andpivoted upon a common bolt 3, secured transversely in one end of theopening. The free ends of these bars. 2 are slightly beveled, and theyfit against a beveled surface or seat 1 in the end of theretainer-frame. This seat prevents the bars from swinging beyond theopposite side of the frame. The retainerframe is also provided with aplate 4, having a handle 43, secured on raised portions 1. at the end ofthe retainer-frame.

Connecting the two retainer-frames is a v bar 5, having a sto 5 at itsmiddle and stops 5 at its ends. T e retainer-frames are adjustable onthe bar 5, and the stops 5 prevent the removal of the retainer-framesfrom the bar. The stop 5 limits the movement of the retainer-framestoward each other and insures a centering and compacting of the frameson the bar when the device is not in use.

In practice the retainer-frames are placed on the heads of two boltsthat are to be secured, as many of the bars 2 being turned up as may benecessary to provide a sufiicient o ening to permit the frame to beplaced on t e bolt-heads, and yet prevent the bolts from turningtherein, after which the nuts can be turred up as tightly as desired.The fact that the device is engaged with two bolts of course prevents itfrom being turned with the bolt.

In Figs. 1, 2, and 3 one only of the bars 2 is turned up; but in Fig. 4five of them are turned up, because the bolt-head therein shown is ofgreatly larger size. With this construction the device is not onlyadapted to bolts that be placed at various distances apart, but it isalso ada ted within limits to bolt-heads of many di 'erent sizes.

What I claim, and desire to secure by Letters Patent, is

1. A bolt-retainer comprising, in combination, a pair of retainer-frameshaving openings therein, a series of bars pivoted in said frames, andmeans connecting said frames whereby they are adjustable with respect toeach other.

2-. A bolt-retainer comprising, in combination, a pair ofretainer-frames having openings therein, a series of bars pivoted insaid frames, handles on said frames, and means connecting said frameswhereby they are adjustable with respect to each other.

A boltretainer comprising, in combination, a pair of retainer-frameshaving openings therein, a series of bars pivoted in said frames, a barconnecting said frames whereby they are adjustable with respect to eachother, said bar having stops to prevent the removal of the framestherefrom.

4. Abolt-retainer comprising, in combinaprevent the removal of theframes theretion, a pair of retainer-frames having openfrom.

To ings therein, a series of bars pivoted to said In testimony whereof Iafllx my signature frames, a bar connecting said frames and on inpresence of two witnesses.

5 which they are adjustable with reference to JOHN HARlMAN each other,said bar having a stop to limit the Witnesses: inward movement of theframes thereon, and SAMUEL E. MORRAL said bar also having st-ops nearits ends to W, W. MORRAL.
